31 Claims. (CL 12-123) hold a lasted shoe so that it may be moved freelyfrom one position to another during the spraying. 7

Heretofore it has been the usual procedure for an operator to hold alasted shoe in one hand within a spray booth and to apply the desiredmaterial to the shoe with a spray gun held in the other hand. Thishandling of the shoe resulted, at times, in soiling the shoe which, in

turn, tended to interfere with secure adhesion of the coating material.sprayed material was bound to be deposited on the operators fingers andfrom there would pass to shoes subsequently handled. Altogether it wasan untidy procedure. 7

It is an object of the present invention, therefore, to provide asupport for a lasted shoe, so arranged that the shoe may be turned fromone position to another without being touched by the hands of theoperator and so constructed that the last may be mounted and dismountedwith the minimum amount of efiort on the part of the operator.

In order that the lasted shoe may be moved readily into substantiallyany desired position to facilitate the application of sprayed material,the support for holding the lasted shoe is provided with a last pinhaving means for retaining the last thereon regardless of the positionto which the last is turned. The support and consequently the last pinare movable in an are about a vertical axis,'and the last pin is movableangularly about a horizontal axis and rotatable on its own axis. Theaforementioned movements may take place in any order of sequence so thatthe supported last may be moved freely from one position to another.

In one of its preferred forms, as illustrated herein, the last pin isprovided with locking means which will serve to retain a normal last.Occasionally, howeven lasts are foundfin which the thimble hole is of anunusual size 'or is worn Moreover, some of the to such an extent thatthe relativelysmall range afforded by the, locking means of the last pinreferred to above is insufiicient to provide proper gripping action. Toprovide for these unusual cases, another embodiment of the invention isshownherein in which the last pin comprises two members arranged to lieside by-side with their inner faces in adjacent substantially partherebyto allel planes face to face, one of the members being adapted to bemoved relatively to the other so that the last pin may be expanded orcontracted. In this embodiment there is provided means associated withone of the members whereby itis urged to turn to a position in which itsface lies at an angle to the corresponding face of the other memberthereby to expand the last pin to lock a last thereon, and'means toreturn the members to nonangular position contract the last pin torelease the last.

In some classes of Work it is desirable to be able to mount the last onthe last pin and remove the same therefrom without manipulation of thelocking means, thereby relieving the operator to a great extent andpermitting faster operation. To this end, thelast jack, including itslast pi'njmay "be mounted on a support so that it may be moved'fromaloading position to an operating position, the movement "of the jackfrom the-loading to the operating position automatically locking thelast on the last pin, and the return of the jack from the operatingposition to the loading position releasing the last. A feature of thisconstruction resides in means for preventing movement of the last pinwhileit is in its loading position.

Several specific embodiments of the invention will now be described withreference to the accompanying drawings, in which Fig. 1 shows anelevation of the support and the last jack, the latter being in section;

Fig. 11 illustrates a counterbalance'for the arbor is supported in ahorizontal position. A collar I6 is fastened to the inner end of thearbor by a pin IS, the collar retaining the arbor in place. A washer 26is disposed between the collar and the inner end of the sleeve [2, thewasher being formed of some material which will afford frictionalresistance to turning when the collar I6 is drawn up tight against thewasher. Another washer 212 is placed on the arbor l against the outerend of the sleeve l2 and forms a bearing surface for one end of a coiledspring 24 surrounding the arbor, the opposite end of the spring abuttinga collar 26 slidably mounted on the arbor. may be adjusted on the arborto vary the compression of the spring 24, a set screw 28 looking thecollar in the selected position. By adjusting the position of the collar26, the friction be- The collar 26 tween the collar l6, the washer andthe inner" end of the sleeve l2 may be varied to control the turning ofthe arbor in the sleeve.

The inner ends of the yoke-shaped arm 14 are joined by a verticallydisposed sleeve 36 (Fig.

9), the latter being pivoted to a bracket 32 by means of a pintle 34whereby the yoke-shaped arm I4, the arbor l0 and the last jack'P may beswung as a unit in a horizontal plane about the vertical axis of thepintle.

The free end of the arbor I0 is enlarged at 36 and is provided with abore 38 adapted to receive the last jack P and to hold the same formovement angularly about the horizontal axis of the arbor and rotatablyabout its own axis. The

last jack comprises a sleeve 4!) reduced at one end at 58 (Figs. 1 and9) to provide one part of a two-part last pin, the sleeve occupying thebore 38 and being retained therein by a C-shaped head 42 the lower arm Mof which bears against one side of the enlargement, and by a collar 44which bears against the other side of the enlargement, the collar beingfixed to the sleeve by a set screw 46. The upper arm 48 of the O-shapedhead is provided with an aperture 50 to receive the neck 52 of a handle54, the handle being fixed to the arm 48 by a set screw 56, asillustrated. The provision of the handle 54 permits the operator to turnthe last jack about its own axis, about'the horizontal axis of thearbor, and to swing it in a horizontal plane about the vertical axis'of:the pintle without touching the lasted shoe which is mountedon the lastpin (Fig. 2) and locked thereto, as will now appear.

The part 58 of the last pin is made slightly smaller in diameter thanthe insidediameter of a standard last thimble 60 (Fig. 2) so that thelast L may readily be placed thereon without using force. The other partof the last pin shown at 62 is of substantially the same diameter as thepart 58 and affords means for locking the last on the last pin. The part62 is disposed below the part 58 in alined end-to-end relation therewithso that in one position (Fig. 1) the part 62 forms a concentricextension of the part 58 of the last pin and in another position (Fig.2) it is eccentric to the part 58. The eccentricity which may beobtained between the part 58 and the part 62 within the confined spaceafforded by the last pin thimble 60 is suflicient to bind the last Lupon the last pin.

The part 62 is formed at one end of a spindle I 64, the axis of which issubstantially parallelto the axis of the part 58 and offset therefrom sothat rotation of the spindle (54 -turns the part 62 from a concentric toan eccentric position with respect to the part 58 and vice versa wherebythe last may be locked on the last pin or released and removed from thelast pin at will. To this end, the sleeve 40 is provided with a bore 66arranged longitudinally thereof, the bore extending through the part 58of the last pin. The bore is eccentric to the axis of the part 51 andreceives the spindle 64. A lever 68 whereby the spindle 64 may be turnedin the bore is mounted near the opposite end of the spindle and issecured thereto by a pin 16 (Fig. 3). The lever 68 is provided with ahub 69 which surrounds the end of the spindle, the free end of the hub69 being journaled in a recess 12 formed in the neck 52 of the handle54. A coil spring 14 is placed about the hub 69 under torsionaldisplacement, one end of the spring being anchored to the handle 54 andthe other end to the lever 68, as illustrated in Fig. 1. The forceexerted by the spring 14 turns the lever, and consequently the spindle64, to a position in which the part 62 of the last pin is eccentric tothe part 58 (Fig. 2) The lever 68 terminates in an extension H having ahandle or thumb-piece l6 integral therewith which serves as a meansforturning the lever in opposition to thespring so that the parts 58 and62 are brought into concentric relation, thereby releasing the last. Inorder to prevent the part 62 from being moved beyond the point ofmaximum ecentricity, and also to limit the degree of eccentricity, anadjustable screw 13 is mounted on the extension 1 I, the end of thescrew being arranged to abut the lower arm 4| of the head 42.

' To prevent relative turning movement-between the last and the lastpin, a depending flange 19 is arranged to engage the neck of the last(Fig. 2). This flange is formed integral with a collar 15 which ismounted on the part 58 of the last pin against the collar 44 and isfixed to the last pin by means of a set screw 11.

The weight of the last and the lasted shoe fixed to the end of the lastpin constitutes a turning moment which, if the arbor I0 were freelyrotatable, would be sufficient to turn the arbor ID in thesleeve 12,thereby causing the last to fall to theposition shown in Fig. 2 wheneverthe operator releases his hold on the knob 54. This would be a nuisanceand result in a waste of time since the operator would have to move thelast back each time it fell out of position and, furthermore, it wouldnecessitate the constant employment of one hand to hold the last inposition. The washer 26, thespring 24, and the collar 26 are, therefore,provided to counteract the turning moment so that the last will remainin whatever position it is placed without manual holding. By adjustingthe position of the collar 26 on the arbor, the compression of thespring 24 may be varied to increase or decrease the bearing pressure ofthe collar l6 on the washer 20. By proper adjustment the frictionalresistance to turning may be set substantially to equal the turningmoment of the last at the end of the last pin so that the arbor will notturn unless manual turning force is applied to the handle 54 or to thelast.

- while there has been considerable progress in standardizing the sizeof the lastthimble hole, it is quite common to find lasts with thimblessmalleror larger than standard thimbles and frequently with thimbles soworn that the last pin described above does not have sufificient rangeto insure locking. A, modified form of the invention designed to meet agreaterrange or variation in the size 'of the thimble holes isillustrated in Figs.

form lies in certain changes in the last jack P,

the method. for supporting the same and the support being identical inevery respect to that previously described. In this form the last jackcomprises a sleeve 88 arranged to extend through the bore 38 in theenlarged end 36 of the arbor I8, the upper end of the sleeve havingintegral therewith a.c-shaped head 82 the lower arm 84 of which bearsagainst the enlargement. The lower end of the sleeve 88 extends belowthe enlargement and a substantially semicircular portion 86 of thesleeve is cut away flush with the lower surface of the enlargement. Asemicircular plate 88 is seated in the cut-away portion of the sleeveand is screwed to the sleeve against the enlargement whereby the sleeveis held in the bore. A semicylindrical member 98 is formed integral withthe plate 88, the member extending downward, as viewed in Fig. 5, andforming one half of a last pin. The plate 88 is also provided with adownwardly projecting flange 92 for preventing relative movement betweenthe last pin and the last, as heretofore described in connection withthe first form of the invention.

A spindle 98 is rotatably mounted in the sleeve 88 and an extension 94formed at one end thereof forms the other half of the last pin the twohalves of the last pin lying side by side with their inner faces inadjacent substantially parallel planes. A lever 98 is fixed to thespindle 95 by a pin I88, the lever serving to turn the spindle in thesleeve. The upper arm I82 of the C-shaped head is provided with anaperture i8 3 for the reception of the neck I86 of the handle I88 whichis fixed to the arm by a set screw H8, A recess I22 is formed in theneck of the handle and serves as a bearing for the free end of thespindle 96. When the spindle is turned in the sleeve, the movable half94 of the last pin will turn angularly with respect to the fixed half 98of the last pin on an axis through one of its longitudinal edges, asshown in Fig. '7. Since the spindle 86 turns on its own axis toaccomplish this turning of the movable half of the last pin about alongitudinal edge, the halves of the last pin are arranged to lie onopposite sides of one diameter of the spindle 95, as illustrated inFigs. 6 and '7, so that the longitudinal edge of the movable half of thelast pin lies substantially along the axis of the spindle 96.

The spindle 96 is turned in one direction by a spring H8 disposed undertorsional displacement .about the free end thereof, one end of thespring being anchored to the handle I88 and the other end to the lever98. The spring normally holds the spindle so that the parts of the lastpin are of the last pin is turned with respect to the fixed half. Toeliminate this, a semisegmental strip has been removed along thelongitudinal edge II8 of the movable half of the last pin, as

shown in Figs. 6 and 7. To prevent damage to the last pin, for example,by forcing the movable half of the last pin in either direction, and tolimit the degree of opening so thatthe operator will not have to movethe thumb-piece through its full range when working with lasts havingsmall thimbles, limit screws I28 and I22 are provided (Fig; 8). Thescrews are adjustably threaded through the back portion of the C-shapedhead 82 and their ends are arranged to bear against the lever 98.

In using the device, as shown in Fig. l, the thumb-piece I8 is pressedto aline the parts 52 and 88 whereupon the last is placed upon the lastpin and the thumb-piece is. released, thereby locking the last on thelast pin. A similar procedure is followed when using the device shown inFig. 5, that is, the thumb-piece H6 is pro- .vided to close the parts 98and 94 of thelast pin, the last is'placed upon the contracted pin, andthe thumb-piece is then released, thereby locking the last on the lastpin.

In the two forms of the invention just described the operator mustmanually operate the locking means during the mounting and dismountingof the last. In some classes of work it is desirable to have a last jackupon which a last may be placedand removed without manipulation, whichnaturally relieves the operator to a great extent and permits fasteroperation. To this end, the last jack illustrated in Figs. 1 to 4 may bemounted on amodified support whereby movement of the last jack from aloading position to an operating position automatically locks the laston the last pin, and the return of the last jack from operating positionto loading position releases the last. When the last jack is so mountedthe thumb-piece on the lever68 may be omitted.

As illustrated in Figs. 9 to 11, the arbor I8 is mounted in the sleeveI'2, as heretofore described, but the spring 28 is omitted, therebypermitting movement of the arbor. longitudinally in the sleeve I2. Inthis form the turning moment produced by the last at the end of the lastpin is offset by a counterweight to be described'hereinafter and,therefore. the friction washer 28 and collar I6 are replaced by a washerI23 and bolt I25 which serve only to retain the arbor in the sleeve.

The last jack in Fig. 9 is shown in what will be hereinafter called itsloading'position, that is, in

readiness for receiving the last. In this position the part 62 ismaintained in a position concentric with the part '58 of the last pin 48by a cam roll I28 (Fig. 10) arrangedv to co-operate with the lever 68,hereinafter in this form of the invention called the cam dog, to preventthe cam dog from being turned by the spring I4 and thereby to hold thespindle 84 in such a position that the part 62 is concentric with thepart 58. The cam roll I 26 is mounted on a stud I 28 carried by one armI38 of a fork-shaped member I82 secured to the free end of the sleeve I2by.

means of screws I3 3. The arms I38 of the member I32 extend alongopposite sides of the C- shaped head 42 and prevent rotation of the lastjack in the enlargement 38, and also prevent angular rotation of thelast jack about the horizontal axis of the arbor I 8.

The last jack may be moved from the aforesaid loading position to aposition to be hereinafter called the operating position. To move thelast jack into operating position, the operator places the last upon thelast pin in the loading position (Fig. 9) and then pulls on the jack orthe handle 54 to move the arbor I8 to its extended position with respectto the sleeve I2. During this movement, the C-shaped head 82 clears theends of the arms I38, and the cam dog 68 is removed from the restraininginfluence of the cam roll I26'so that the cam dog 68 is of the UnitedStates mounted on said turned by the spring I4, thereby causing the part62 to grip the last thimble 6!] (Fig. 2). In

the operating position it is clear that by grasp- 'last pin, will remainin whatever position it occupies when the operator releases his grasp onthe handle. This is accomplished-in the present instance (Fig. 11)by'placing a counterweight I36 on the end of an arm I38 which is securedto a collar I40 surrounding the neck 52 of the handle 54. Thecounterweight I36 is movable longitudinally of the arm- I38 and may befixed at any position along its length by means of a set screw 32. Theadjustment provided by this arrangement permits the operator to obtain asubstantially perfectbalance for any last mounted on the last jack in.spite of-the variation in weight of different lasts.

After the spraying or coating operation has been completed, the operatorpushes the last jack back toward the loading position to release thelast. Preparatory to this operation, however, the C-shaped head '42 mustbe turned to such a position that it will readily enter the spacebetween the arms I30 of the member I32. In order to relocate theC-shaped head 62 in the proper position, a spring-pressed plunger I44 isprovided in the enlargement 36 which co-opcrates with a recess I46formed on the under surface of the E'C-shaped head so that theoperatormay turn the handle. 54 until he feels the spring-pressedplunger snap into the recess M6. The last jack may then be moved backtoward the sleeve i2 and the C-shaped head will be in proper position tomove between the arms I30 without interference. As the last jack ispushed into position between the arms I30, the cam roll I26 will engagethe cam dog 68 and turn it radiall into the position shown in Fig. tobring the part 62 into concentric relation with the part 58 of the lastpin, whereuponthe lasted shoe will fall from the last pin.

In operation, therefore, it is clear that the operator may with one handplace the lasted shoe upon the last pin, move it into operatingposition, turn it while in operating position so that access may be hadto all parts of the shoe, return it to the loading position, and releaseit, while he holds the spray gun in the other hand.
